sm-nnsuame s'rocx 1 1 To azzwmam concem:

Be it known that I, FRANK W. Wnsrnn,

Reynolds, in the county of Grand Forks and State of North Dakota, have invented certain new and useful Improvements in Self- Measuring Stock Feeders; and I do herebydeclare' the. following to be ajfull, clear, and

'exact description of the.- invention, such. as

will enable others skilled in the art to which it appertains to make and use-the same.

Thls invention has relation tocertain new and useful improvements in self measuring stock feeder and has for its-primary'object," the provision of a self measuring stockfeeder of the above stated character in which the valves will be mounted in a novel manner and resiliently retained in normal posie ease tion so that after the operation to r the predetermined quantityofi'stock, the valves will be returned 'to normal position to permit the feeding or measuring tube to be again filled from the-supply receptacle or. tank above the same communicating therewith. I

.With the foregoing and other 1 objects in f view, as will be hereinafter more specifically set forth, pointed out in the appended claims and shown in the-accompanying drawings forming apart of this application,

the invention consiststin the novel-construction, combination and arrangement of corating'elements as disclosed in'this app 'cation. p 1 n In the drawings forming a part of the ap licatiomigure 1 is a side elevation of the structure embodied in this invention.

' eferrin'g. more in detail to the drawings in which: similar referencecharactels designate corresponding parts throughout the several views, 1 indicates a suitable feed supply receptacle from'iwhich depends the feed tube 2,'the lowerfportion of which is I 'increased'in width'byv having one side open and the parallel side supporting members or plates 3' extended from the opposite edges ofthe open side .of the lowermost tube 2,

as clearly-shown: in the drawings. A pair of pivot pins Land 5 are mounted -in'the lever supporting'plates fii, outwardly of the lower portion of, the tube 2, as clearly shown inxFigures Into 4 inclusive of the drawings.

The main or primary valve and operating lever '6 mounted upon the upper and innerm'ost pivot *pin 4, and includes an upwardly and outwardl extended portion 7 and a lower outw 1y curved portion 8. This member alsoincludes a horizontally directed valve '9, above the pivot point of the member and which extends transversely through the tube 2. at the upper end of the plates 3, this valve plate 3 projecting through a slot 10 in the rearwall ofthe tube 2 and having downwardly directed fingers 11 to limit inward movement of the valve plate '9 through the tube 2 in one direction. The val'veplate 9 has a-transverse slot 12 which with the passage of the tube-2 when t e primary valve and 10 rating lever 6'.-is in normal position. member 6 isresiliently retained in normal position by thespring 13 which has one end secured to the, upper portion 7 of the member-.16 while its-opposite end is secured to the opposite side'jw'all of the tube 2, as clearly shown'inthedrawings.

Auinte 'ediate lever 14 is employed and has depending leg portions 15 which are turned -with'respectto the main portion of the, lever 14 and'pivotally mounted on the 'ivot pin 4. The main or upper portion of t is lever 1a is rmflienfly retained in spaced relation with respect to the upwardly 7 of the nun as clearly shown in Figure 3 of the draw- 7 I ings.

The secondary valve 17 has a curved lower end 18 which is normally in contact with the rear wall of the tube 2, adjacent the lower ends of the plates 3. This valve 17 has a number of opposed teeth 19 along its opposite edges and directed outwardly to form notches 20 to receive the pivot pin 5 so that the secondary valve may be readily adjusted with respect to the primary valve and operating lever 6 so as to, vary the amount of feed to be delivered each time the valves are operated. The parts are so arranged that the lever 14: engages the inner face of the secondary valve 17 ad'acent the upper end thereof, as shown .in 3, while the outwardly curved lower end 8 of the member 6 contacts with the inner face of the secondary valve 17 at a point below the pivot pin 5. It will therefore be seen that when the upper end 7 of the member 6 is pressed inwardly toward the tube 2, to close the tube 2 by the solid portion of the valve plate 9 being forced across the tube at the upper edge of the plate 3 orthe measuring compartment as it may be termed, the secondary valve stem will be forced outwardly, thereby forcing the lower curved end of this valve away from the wall of the tube 2 to permit the feed between the valves 9 and 17 to pass out of the tube 2. As soon as the primary valve and operating lever 6 are released, however,

the'springs 13 and 16 will act to return the valves and all movable .parts to normal -posi-' tion, thereby again closing the tube 2 at its lower extremity by the curved end 18 of the secondary valve 17 and. opening the tube 2 at the upper ends of the plate 3 or feed. measuring pocket by again bringing the transverse slot 12 of the valve 9 lnto re 'stration with the tube 2.

t is believed. that .the complete construci gure tion and operation of this invention may be understood by reference to the drawings without further detail description. It is evident, however, that minor changes in the details of construction and arrangement of parts may be resorted to Within the scope of the appended claims without departing from the spirit of the invention.

What is claimed is A 1. A device of the class described having a dispensing portion, a lever to normally close the portion, an operating lever one end of which is in contact with said first named lever, means to urge the levers into such contact, means to normally urge the second lever at the other end awa from the dispensing portion, and a cut-0 valve for such portion operable by the second lever. 2. A device of the class described having a dispensing portion, a lever to normally close the portion, an operating lever one end of which is in contact with said first namedlever, means to urge the levers into such contact, consisting of a plate pivoted to one of the levers and bearing against the .other lever, and an expansive spring bearing against the plate and the opposite lever.

3. A device of the class described having a dispensing portion with side walls and an end wall, a lever intermediate the side walls with its end normally in contact with the end wall, a second lever intermediate the side walls serving as'an end wall thereof,

In testimony whereof I aflix my signature-90 in presence of two witnesses.
